The civil twilight has just ended and it's time for the nautical twilight. In a dark blue sky, the stars are slowly appearing. At the end of the nautical twilight (which marks the beginning of the astronomical twilight), they are numerous. And the Milky Way is now visible. Faint at the beginning, it is more and more contrasted as the astronomical twilight is going on. At the end of the astronomical twilight, it is the deep dark night.
